39. Note that our approach would not work in the absence of a thermostat: to describe rotational motion properly, one would need to define orientations and angular momenta in a local reference frame that moves with the extended object to which the oriented point particle belongs. In this manner, rotational motion of the extended object gets propagated down to the angular momenta of the particles it consists of (A QSHAKE algorithm would in addition be needed to properly conserve angular momenta in the constraints). While this approach is computationally significantly more cumbersome, we expect the result to be similar for the above model, in which rotation of extended objects is propagated down to its constituting particles through angular potentials and an overdamped thermostat.
